Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface, and the ignition is off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Clean Wheel Speed Sensors

Remove the wheel hub covers if applicable.
Unbolt and detach the wheel speed sensors from the wheel assembly.
Clean any dirt or debris from the sensor and mounting area using a soft cloth.
Reattach the sensors securely and ensure wiring connectors are firmly plugged in.

3. Check Brake Fluid and System

Inspect the brake fluid reservoir and top off with the recommended fluid type (DOT 3 or DOT 4).
Examine brake lines for visible leaks or damage.
If leaks are found, replace damaged components (hoses, calipers, etc.) before continuing.

4. Inspect Traction Control Module

Locate the traction control module (usually near the ABS unit).
Check for loose or damaged wiring and connectors.
If necessary, perform a continuity test using a multimeter to ensure proper electrical connections.
Replace the module if any faults are detected.

5. Verify Tire Condition and Pressure

Check each tire for proper inflation according to the manufacturer's specifications (usually found on the driver's door jamb).
Inspect tires for wear or damage; replace if necessary.
Ensure all tires are of the same type and size for optimal performance.

6. Reconnect Battery and Clear Codes

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any fault codes from the system.
Start the vehicle and observe the traction control light.
